We attain these and other objects of our invention by the device illustrated in the accompanying drawing, in which,- 7

Figure 1 is a perspective view of our invention;

Fig. 2 is a longitudinal section through the back of our'brush, the handle and paintdelivery pipe being shown in side elevation, a portion of the handle, however, being broken away to show the mounting of the paint delivery brush in same; and

Fig. 3 is a verticaltransverse se our paint brush.

Like numerals designate like parts in each of the several views.

Referring to the accompanyingdrawing, we provide a brush 1 having an opening or chamber in the center of the brush back and having front and back rows of bristles forming. the brushes 3, as shown in Fig. 2. These brushes 3 are preferably wire brushes, or spaced rows of bristles with an intervening strip of folded asbestos or other material folded into a close U shape.

Mounted on each of the sides of the'brush back are two metal strips or blades 4, as shown in Fig. 3, which are provided with vertical slots 8 through which are inserted bolts 5 having nuts 6 and washers 7 to permit of a free vertical movement ofthe blades as the brush is moved along on the roadway or'street.

We provide leaf springs 9 mounted by means of suitable brackets 10 onthe brush'back 1 and having the free ends of the leaf springs resiliently engaging the upper edge of the metal blades 4, as best shown in Fig; 1. We provide a metal strap 11 fastened to the hollow handle 17 and to the brush back 1 by a bolt or screw12. We also provide metal straps 13. secured to the metal handle 17 by suitable rivets 151 and to a fasteningfplate 16 by a pin or bolt 15, a plate 16 in turn being" suitably aflixed to the front portion of the brush back 1, as shown in Fig.2. I-Iollow handle 17 is provided with a removable cap 18 to permit of filling the hollow handle with suitable paint.

The paint delivery. pipe 25 is 5 preferably flared at its lower end, as shown in Fig. 3. V

In operation the cap 18 of hollow handle 1'? is removed to permit of filling the hollow handle with paint. The valve 24 in .paint delivery pipe 5 ting the handle portion 21 of lever 19 which is operatively connected with the valve, diagrammatically shown at 24, and which may be any suitable valve. The paint flows onto theroadway or street and is spread by the brushes 3 while it is prevented from flowing out laterally to anyv extent by the blades 4 which automatically adjust themselves to the contour of g the roadway as they are loosely mounted for vertical sliding movement by means of the-slotsx8 and the bolts 5 through said slots. The metal blades or sides 4 function as runners and to some extent support the brush, no wheels beingnecessary.
